Good morning! Today’s microbiome digest is brought to you by mild insomnia induced by a mid-afternoon coffee. It includes two food related studies, one on pathogenic E. coli found in ready-to-eat foods and the other focused on a antifungal lipopeptide produced by B. velezensis isolated from honey, and an an article focused on a new approach for processing frozen lung and lavage samples for use in microbiome studies. Also included are several articles focused on the gut microbiome, and several preprints focused on soil microbiome studies. Finally, I want to highlight a piece that details the positive outcomes associated with the National Summer Undergraduate Research Project (NSURP). Registration for this year’s program is still open until April 15th, and the organizers are looking for both mentors, mentees, and donors!

Today’s digest covers a range of topics including a duplex qPCR assay to detect lung infections, an investigation into sand fly symbionts, and a characterization of a fermented soybean food (Pe poke). If you want to end the week on a good note, I’d suggest reading the two articles I’ve highlighted below. One demonstrates that flooding and ecological restoration of former cranberry farmland also restores wetland microbial communities and soil function. The second provides a new barcoding strategy for the phenotypic screening of mosquitos that can be applied towards malaria research.

Sorry for the delayed post, WordPress was playing some mean tricks on me today and there were no treats! Good morning all and happy spooky season! It’s been a moment since I’ve written a post and I write to you now as a freshly (pepper)minted PhD! I’m feeling gourd and can’t wait to pumpkin spice things up with some fangtastic papers.

Some of the highlights include a paper by McAlpine et al. examining interkingdom relationships between bacteria and fungi. Specifically, they found that the gut commensal species Lactobacillus can produce a small molecule that blocks filamentous growth of the opportunistic pathogen Candida albicans. Another interesting paper comes from Michael Adams lab at the University of Georgia, Athens which showed that members of the gut microbiota have the capacity to assimilate the metal tungsten which, in turn, allows these microbes to oxidize a broad range of aldehydes in the gut. Additionally, a paper by Plummer et al. looked at the vaginal microbiota of women who have recurrent bacterial vaginosis as well as the penile microbiota of their partners, and found that when males also underwent antibiotic treatment it led to a decrease in bacterial vaginosis in their female partners.

Hope you enjoy reading these fa-boo-lous papers and may you eat, drink, and be scary this Halloween!
